2. Figure 1
Plots of the standardized differences for baseline covariates between patients who received the mechanical valve and patients who underwent the Ross procedure, before and after propensity score matching. CABG = coronary artery bypass grafting; EF = ejection fraction; LVEDD = left ventricular end-diastolic dimension; LVESD = left ventricular end-systolic dimension; NYHA = New York Heart Association.
